PetscDrawLGCreate#

Creates a line graph data structure.

Synopsis#

#include "petscdraw.h"  
PetscErrorCode PetscDrawLGCreate(PetscDraw draw, PetscInt dim, PetscDrawLG *outlg)

Collective

Input Parameters#

  • draw - the window where the graph will be made.

  • dim - the number of curves which will be drawn

Output Parameter#

  • outlg - the line graph context

Notes#

The MPI communicator that owns the PetscDraw owns this PetscDrawLG, but the calls to set options and add points are ignored on all processes except the zeroth MPI process in the communicator.

All MPI ranks in the communicator must call PetscDrawLGDraw() to display the updated graph.
